13th June 2022, the gRPC has changed a bit. The generated code for services and messages are now in separate folders ending with _grpc.pb.go and .pb.go respectively. Also, 1. At the top of the proto file you need: `option go_package="/currency";` 2. The command for generation can now be something like this: `protoc -I protos/ --go_out=. --go-grpc_out=. protos/currency.proto`

Couple of additional things: Currency struct should be changed to this: type Currency struct { log hclog.Logger protos.UnimplementedCurrencyServer } and also implement this func as well: func (c *Currency) mustEmbedUnimplementedCurrencyServer() {}

Great video, I was able to utilize this for my first GRPC concept build. Really I'm just a hobbyist but I appreciated the method of your approach. Too often people don't take the time to explain the fundamentals of things first (explanation on proto was perfect). If I had time to read the entire documentation I wouldn't be looking for a youtube video to jumpstart me.

Another change is that proto grpc now requires generated servers to have forward compatibility. To fix the error, add protos.Unimplemented*Server to your struct (no field name needed) and also add in your constructor. Or, you can opt out of forward compatibility by adding protos.Unsafe*Server instead, or change your protoc to have this command: --go-grpc_out=require_unimplemented_servers=false:.

Has there been some large change in the golang grpc package since the time this video was made? I used the command "protoc --go-grpc_out=. path/to/file.proto" to generate my currency_grpc.pb.go file and it looks drastically different than yours.

awesome video, one little detail: for me when i followed the steps i had `Base`, `Destination` and `Rate` in json (PascalCase instead of lowercase) also, i don't have the `[json_name = "xxxxx"]` part when i describe a message. tested it today
@knabbagluon4 жыл бұрын
message RateRequest { // Base is the base currency code for the rate string Base = 1 [json_name = "base"]; // Destination is the destination currency code for the rate string Destination = 2 [json_name = "destination"]; } With this it works. I don't know why he doesn't have to write it. I will find out eventually.

okei, it breaks my heart when intellisense fails in your .proto file, when generating go modules, you can write `option go_package = "";` some where else in your project you can call stuff from that package. .MyStruct.

19th April 2023, you need to add "UnimplementedCurrencyServer" to the Currency struct for forward compatibility : type Currency struct { protos.UnimplementedCurrencyServer log hclog.Logger } func NewCurrency(l hclog.Logger) *Currency { return &Currency{log: l} }
